Chemical herbicides are currently one of the most common methods for managing aquatic invasive plants. Despite their widespread use, little is known about the potential negative effects that several of the most commonly used herbicides may have on vertebrates. Amphibians may be particularly at risk because they can easily absorb toxic substances through their skin. In a controlled chamber experiment, Northern Leopard frogs (Lithobates pipiens) were exposed to environmentally relevant concentrations of copper-sulfate and diquat-dibromide, two herbicides commonly used to control invasive aquatic plants. The effect of these herbicides, either alone or combined, were evaluated on survival and growth-related traits of tadpoles over the course of the experiment. Tadpole survival was significantly decreased by copper-sulfate applications and the combination of this herbicide with diquat-dibromide. The copper-sulfate treatment also negatively affected the growth of tadpoles throughout the experiment, as evidenced by lower measures of body weight and body length. Conversely, diquat-dibromide caused a significant increase in tadpole growth, although it was only a transient effect. This study provides relevant information regarding the potential effect of two herbicides (commonly applied simultaneously) on an amphibian species that is considered to be an indicator of the quality of natural wetlands. Therefore, it has important implications for the management of aquatic environments that provide habitats for a multitude of non-target species.
